From the introduction:
This is the true history of Gaia and her children. Characters that believe this version of events will encounter hostility from Ptah and his minions.
Legends of the Dark Wheel presents a well-developed science fiction/starfaring setting to the !G - Rated G role-playing system. This same setting was previously published by the author as Epitaph, a setting for the Fudge system. Additionally, comments are included for conversion from the Talespinner system. The setting includes locales, history, personas and organizations, and geography. Additional sections include place-specific activities (e.g., gambling or shopping).
